Message Instead of the circuit going:

Boost -> T -> [Wastegate] and [Safety Boost -> MBC -> Suction]

It is plumbed:

A) Boost -> MBC -> T -> [Wastegate] and [Safety Boost -> Suction]

Correct?

Or is the safety boost gone altogether?

B) Boost -> MBC -> Wastegate

A would likely cause your wastegates never to open, and your boost would be high.

B (No safety boost solenoid) should work as a pressure differential and cause your wastegate actuators to open at a higher pressure (assuming you have the MBC closed to some degree)

Are you seeing '5psi' with the MBC fully closed?
